DeepSeek Harness (DSH) 插件：在模型读取前撤回已发送的文字消息，支持单条与全部撤回。A DeepSeek Harness plugin that recalls sent-but-unread text messages before the model reads them — one-by-one or all at once.

DSH 实现 workbuddy 同款选择 skill 功能 | WorkBuddy-style skill picker for DeepSeek Harness: pick a skill in the composer, insert the official /skill-name gesture, and DSH loads it with your message.
